Zack stared at the sight of his sister presenting herself in such sexy lingerie. As hot as the sight was he wanted to see her body presented to him fully nude.
Carla purred, "Like what I'm wearing my sweet brother? Or do you want to see me fully nude?"
Zack his voice husky, replied, "Fully nude, my sweet twin."
Carla felt her pussy tingle wildly, presenting herself fully nude for his eyes before he plunged his cock into her, god, what a rush.
The muted light from the nightlight provided enough for Zack to savor the sight as Carla unbuttoned the front of her nightie, then the smile as she gently pushed it from her shoulders, and it dropped to the floor. He saw her crumpled nightie on the floor, now she was gloriously naked, approaching him with a hungry expression.
The sight of his sister, a self-described cum slut, made his lust roar. From her 34D chest, down to the sexy curve of her waist, and the tight little coin slot of her bare bald pussy lips, she spun, and let him gaze at the perky cheeks of her ass, those glorious globes looked so firm yet squeezably plump. Seeing his sister so hungry for him had him stiff as a steel bar.
Carla cooed, "Stay laying back Zack, and let me give you a hot cowgirl ride."

In Carla and Laurie's room, Laurie was laying back, naked and stroking gently at her mons, the 7-inch dildo at the ready. She was waiting to hear the chorus of fucking from her parents to start the show. She had talked about it with Carla, and Carla was going to mount Zack just as their parents started fucking, she would impale her sweet cunt on Zack's cock, and the house would be full of hot fucking action.

In the master bedroom, Melissa sashayed out of the attached bathroom, she was clad in her black garter belt and black stockings. She knew how much George liked hot sex when she was dressed for the occasion, and his tiger-like hunger never failed to take her over, more than once a session, he was a very virile man. He was breathing heavily, eyes shining with lust, waiting for her on the bed, his 8-inch pussy pleaser standing at the ready.
Melissa had a lust-fueled smile as she sauntered over to the bed, her heart thumping, her eyes locked on that stiff cock waiting for her.
"You ready for me, honey?" Melissa cooed. A vigorous nod was the only answer. "Mmmmm," Melissa sighed, her fingers running up and down the cock, "let's get this big fucker in me, right now!"
She climbed onto the bed and squatted over that formidable cock, letting the juices that were dripping out of her lube up that swollen cock head, she wanted her pussy to take it to the max on the first downslide.
The scene was set, and the house was about to shake and bake.
Melissa nudged against the swollen head, she adjusted her hips and dropped down onto the stiff dick, her loud moans blending with George's grunts of pleasure as she took it in, with one hard downward thrust.
*****
Her moans were heard, and in Zack's room, Carla slipped her cunt down over Zack's cock and dropped down, both of them letting out matching grunts as her pussy was spread open around the hard, stiff 7 inches.
*****
Laurie heard her Mom, and she nudged the dildo against herself and powered it in, mmm, she loved ramming herself in one big push.
*****
Melissa was stuffed, her pelvis pressed tight against George as she was now bonded to her husband by his swollen cock. Melissa paused, leaned forward, and found her husband's lips, coming together in a hot, tongue-filled swirl of pleasure that left them both breathless. Melissa, her voice a hoarse whisper cooed, "Fuck me, lover man, really ream me out!"
*****
In Zack's room, brother and sister had their eyes wide open, staring at each other as Zack's cock was now stuffing his sister's tight little cunt. Carla moved her body down, and when she adjusted herself, Zack got the message. His mouth captured her breasts as they dangled, licking and sucking her nipples, then gently nibbling at them. Mmmmmm she adored getting her nipples sucked like that, it made her cunt creamy wet, and slick.
Carla then ordered, "Fuck me, fuck me hard!" And her hips began to churn, Zack eagerly humped up at her, his rock-hard cock spreading her womanly folds open, the gasps of pleasure starting to fill the room as brother and sister wantonly pleasured each other.
They both groaned and Carla shivered with delightful tingles as Zack's hands grabbed her breasts, gently pinching and twisting them.
